1771: In Virginia, a wall of water came roaring down the James River Valley following ten to twelve days of intense rain. As water swept through Richmond, buildings, boats, animals, and vegetation were lost. About one hundred fifty people were killed as the River reached a flood stage of forty-five feet above normal. A monument to the flood was inscribed by Ryland Randolph, of Curles, in 1771-72: ” … all the great rivers of this country were swept by inundations never before experienced which changed the face of nature and left traces of violence that will remain for ages.”
1896: A massive tornado struck Saint Louis, Missouri killing 255 people and caused thirteen million dollars damage. The tornado path was short but cut across a densely populated area. It touched down six miles west of Eads Bridge in Saint Louis and widened to a mile as it crossed into East Saint Louis. The tornado was the most destructive of record in the U.S. at that time. It pierced a five-eighths inch thick iron sheet with a two by four-inch pine plank. A brilliant display of lightning accompanied the storm.

1997: An F5 tornado killed 27 people in Jarrell, Texas. Although tornado warnings were issued 30 minutes in advance and local sirens were sounded, there were few places to go for safety. Most homes were on slabs, with no basements. Houses were swept clean off their foundations, with little debris left behind. Total damage was $20 million dollars. The same thunderstorm complex produced a wind gust to 122 mph at Kelly Air Force Base in San Antonio.
